Why does my telephone display messages saying "The SIM has sent an SMS"?

Most recently modified:

Mobile ID uses an application on the SIM which, when it is in use, communicates with the Mobile ID service via encrypted text messages. On some phones, the manufacturers have included alerts which are triggered when this occurs. Unfortunately these notifications cannot be turned off by Sunrise. On a few mobile phones it may be necessary to confirm that the SMS has been sent.
